DISINFECTANT.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed October 19, 1906. Serial No. 339,672.

To all whom it may concern:

Be it known that I, MATHIEU SOUVIELLE, a citizen of France, residing atParis, France, have invented new and useful Improvements inDisinfectants, of which the following is a specification.

This invention relates to improvements in compounds for preventing anddestroying the germs of contagious and infectious diseases.

All epidemic diseases are either contagious, infectious or zymotic, andmay be transmitted in various manners, so that it is very desirable thatsome agent should be provided whereby the spread of such diseases shouldbe prevented. I have discovered that by the employment of the agents orcompounds hereinafter described, either by burning, spraying or flushingin infected places, or by taking into the system in any suitable manner,the causes of contagious and other like diseases are eradicated, ortheir effects rendered harmless.

The object of this invention, therefore, is to combine and arrangesuitable prophylactic disinfecting and therapeutic agents that they maybe readily burned in suitable quantities to give off in vapor the agentsactive and desired for the ends sought, or they may be sprayed ininfected places, thereby destroying the germs of contagious andinfectious diseases, or preventing the spread of such diseases, or,furthermore, by immersion in water to impregnatethe water therewith, sothat it becomes, when drunk, a preventive agent. In accomplishing this Iuse as a base for the composition, vegetable tar when it is to be takeninternally, or vegetable or coal tar, or a mixture of both, when thecomposition is burned or sprayed. W'ith either the vegetable or coal taror a mixture of both is combined, as circumstances may require, sodiumchlorid, calcium chlorid and sulfur, and as an example of theproportions of the in redients of the composition is about as fo lows:20 pounds of tar; 3 oz. of sodium chlorid; 3 oz. of calcium chlorid; 6oz. of sulfur. Such composition, when burned, will yield va orsbeneficial to the already affected, whi e sulfurous acid gas will begiven ofi, which is highly destructive to, in fact, totally incompatiblewith germ life, either animal or vegetable.

When the composition is utilized for spraying or flushin purposes theingredients thereof are com ined with a suitable liquid in the necessaryproportions. By way of example such solution may be either lime water oran aqueous solution of bichlorid of mercury, or both, preferably thebichlorid of mercury solution, and 85% of this solution is used with theother ingredients which constitute the composition and then heated tothe boiling point, which causes a unification of the ingredients.

For the destruction of floating germ life and the prevention of thespread of diseases due to the dissemination of such germs, it is betterthat the vapors of such composition arising from its combustion shouldbe used and the combustion extended over some period of time to insurefor such time the impregnating of the atmosphere with such germdestroying vapors. To accomplish this a roll or plate of a suitable baseis impregnated or covered with such a composition. The roll or plate maybe of any desired sizequite small for use in a room or building, ofsufficient size to furnish a base for a large amount of the material forcombustion in the open air. WVhile this base may be metallic with acoating of the composition thereon, or mineral, as asbestos cloth orfiber saturated therewith, a chea and preferable form is a strip orshaving o porous or bibulous wood thoroughly impregnated with thecomposition so that all may burn for some moments of time and thoroughlyfill the apartment or building with the germ-destroying vapors. Such aroll may also be used to prepare a medicated water having propertiesimparted to it thereby which are destructive of germ life and theeffects of germ life in individual cases. stance the roll is thrown intoa receptacle containing water and allowed to remain there for a while,preferably when the medicated water is made the tar, sodium chlorid andsulfur are only used, but if desirable the calcium chlorid can also beused. By its action the water is urified and it becomes im regnated witht e preventive and prophylactic properties of the composition, and whenused as a beverage, aids in the curing of germ diseases and in theprevention of infection and contagion, and, furthermore prepares themucous membrane of the human system to resist any further infection. Inaddition to its uses in a limited space, such as an apartment orbuilding, it may be used in large uantities throughout an entiredistrict, age or city, and is particularly adapted for the In this iniflushing of sewers, and when used in this connection a requisite amountof the prophylactic material in the form of a liquid is flushed throughthe sewer pipes so that the disinfection can take place upon the wallsof the sewers or ipes. When disinfecting a large district, village orcity the prophylactic material is sprayed so as to destroy the germsalready existing in the dust and to prevent their germination, as wellas their evaporation, or, it can be burned if desired, thereby producinggerm-destroyin gases.

If for some hours at the first an then for brief periods for severalsuccessive days, the prophylactic material be burned at frequent pointsin an infected city or district the Vapors mingling with the atmospherewill destroy the life of the germs therein mingled and floating, as wellas revent germination and evaporation, and a so revent the furtherinfection of the city or istrict. In such cases it may be advantageousto use gun powder with which an additional percentage of free sulfur hasbeen mixed, the sulfur retarding the combustion of the gun powder,

while the gun powder insures the combustion of the added sulfur and theconsequent liberation and elimination of a larger percentage ofsulfurous acid gas.

Although it has been stated that the inven tion is used for disinfectinginfected spots, buildings, districts, villages and cities, it is alsothoroughly applicable for use for the na and merchant marines, as wellas in pub 'c or rivate conveyances.

When t e material is used for burning purposes it can be put up in rollsor packages, which constitutes it a new article of manufacture fordomestic or household use, or when used for disinfection of largedistricts it is put up in bulk with some base which insures slowcombustion. When o used for spraying or flushing purposes in liquefiedform it is cles according to the quantity re uired.

The herein described compoun is an imrovement upon Letters Patent N 0.342,231, ated May 18,. 1886, in the followin features: The addition ofsodium chlori and calcium chlorid and extending of the uses of thedisinfectant for spraying purposes and the flushing of sewers, streets,passa es, steamers, trains, and vehicles, and all pu lic conveyances.

What I claim is packed in varying sized recepta- 1. A compositionofmatter for prophylactic, disinfecting and therapeutic purposescomprising twenty ounds of tar, three ounces of sodium ch orid, threeounces of calcium chlorid, and six ounces of sulfur. 2. A composition ofmatter for prophylactic disinfecting and;- therapeutic pur osescomprising vegetable tar, sodium 0 orid, calcium chlorid, sulfur, and asuitable liquid.

3. A composition of matter for prophylactic, disinfecting andtherapeutic purposes comprising calcium chlorid, sulfur, tar and asuitable liquid.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
